Study on Active Micro-vibration Isolation System with Linear Motor Actuator

Abstract

An active micro-vibration isolation control system with linear motor actuators has been proposed and studied. The system is supported by the air springs and symmetrically placed linear motor actuators. A mathematical model of the micro-vibration isolation platform is established, and the optimal control algorithm is designed for isolating vibration system. Simulation and experiment is carried out to verify the effectiveness of active micro-vibration control system. The results demonstrate that the proposed micro-vibration control system has good isolation performance and the linear motor can be used as the active actuator.
